T @ZZ fm1* i Be itl hat il, Winner TPPER, a son )ect ien Emperor,residing; at Kiel @om have invented certain new j :s U Il V andA nsrovernents in Lire Saving Devices .cli the followin@ is a seciti'cation. ce being had therein to the n relates to life-saving; de-"1 signed especially for use in .ing sub-marine boats.

The app r tjes is secured inside of the sub marinebo by a ball andsocket joint, se-

cured in s a manner that it may be opll crateri from within the boat.The

adapted for use by saft which case it is secured to e boat over one ofits openi can ne operated from either e or the salvage vessel.'

rtus consists in an accordionoasing, havingr metal rods ,n..itenedtherein to plates and seing protected by an outer encover, consisting ofrubber, air

velop' ai tight robber coated linen, or the like, so that I air., whichis to be pumped i be retained and gradually force expand upwardly.Between "il d' are provided supports compress-iet therein.

Fig. 4, shows the supports adjusted in three diti'erentpositions. 5, is a bottom view of the life saving device. Fig. 6, is avertical section fastened to the top, or over an opening', in thesub-marine. Fig. 'l' is a cross section, taken on the line A-B, of Fig.6, and Fig. 8, is a cross section showing the parts adjacent 'to thewinch.

The device is composed ot metal plates e equal in size, and fastened toouadrangular frames c2 by means of hinges el, the longest edge ofeachlplate c is again fastened by means of hinges to the next series. insuch n the structure in its lona nanncr that the parts will readily foldup orffoovcr the other y vice.

Between the frames e2, supports are secured which will stretch outwardlyas the device is being pushed out, and will be held in position by theparts t1, so they fall over the joints of the supports t.4 At the lowerpart the devine is provided with a door (l. At the upper end thedevice'has a receptacle g, whichhastat its lower part a door c, openinginwardly, while at its upper part it has a door openingA outwardly andstill a fur ther door b, opening inwardly.

When the device isv notin use it is folded up as shown in Fig. G, sothat its upper surface is fastened to and will rest by its flange on.the detachable cover Z of the defit the lower part of the apparatus a.winch f', is provided, arranged for four ropes an inlet m 'forcompressed air will be found therein hav-ing an outlet in the charnberg. The four suspension ropes are of each rope is fastened to a drum ofthe Windlass f and wound up as far as is necessary. The other end o't'the ropes are passed through all the fluide holes in ythe corners at theinner sides of the bail and they are then fastened to the lid Z (seeFig. l) or to the door d. (See Fig. G.)

.if the apparatus is to be used to save a sunken submarine it. will beoperated from the inside of the boat, as shown in ig. 3, beingconstructed in a casing" A, turnab-le in all directions. When the deviceis to be used from a salvage vessel, it will'be built in a cylindricalshaft C (See`Fig. ti), having a removable cover D, having; at. its lowerpart two connectinp,r curved tubes and le, which are in connection witha valve 0', by means of a door ai.

The operation of the device in a sub-marine, isas follows: When thedevice is being pushed out, or b'eing fastened on to the submarine, thelatter, which may have sunk and be lying on oneJ brought into a.vertical position again. A manen/ill then go troni the boat through thedoor al, which will then be closed after him and the man will proceed oninto the recep# tacie g. From the boat compressed air will now be forcedthrough inlet m into the shaft whereby the receptacle' g will be raisedand after having reached its highest position.
